Ingo Karkat 6ea2b5ae6d Mention all (also XDG) config file locations in help for -d (#343)
* Refactoring: Replace serial checks for `TODOTXT_CFG_FILE` and `TODO_ACTIONS_DIR` with loops

Two fallbacks (like for the actions dir) may still be fine, but we're now supporting so many config locations that a loop is much shorter, and the various locations are much easier to see.

For consistency, also apply this to the actions dir lookup, although it's less of a problem there.

* Refactoring: Apply the first default for `TODOTXT_CFG_FILE` also in the loop

There's no need to handle this separately; either an exported environment variable already exists, or it got assigned via `-d CONFIG_FILE`, or the `test -e` will fail on an empty (or bad non-existing) value, and we enter the fallback loop.

* Mention the actual config file locations in the help for `-d`

Extract the list of default locations into a `configFileLocations` array and join that into a string that then gets interpolated into the help output for `-d` (that so far only mentioned the first default location).

* Comments: Don't favor a single config location in the requirement

* Documentation: Mention `~/.todo/config` as just one of the defaults

As there are several others, now shown in the help for `-d`.

I don't want to duplicate the entire list here, as there's a high risk of those lists diverging.

Will not call any `.todo.actions.d` scripts.
```shell
todo.sh command [ACTIONS]
```
### `deduplicate`
Removes duplicate lines from todo.txt.
```shell
todo.sh deduplicate
```
### `del`
Deletes the task on line ITEM# in todo.txt. If TERM specified, deletes only TERM from the task.
```shell
todo.sh del ITEM# [TERM]
todo.sh rm ITEM# [TERM]
```
### `depri`
Deprioritizes (removes the priority) from the task(s) on line ITEM# in todo.txt.
```shell
todo.sh depri ITEM#[, ITEM#, ITEM#, ...]
todo.sh dp ITEM#[, ITEM#, ITEM#, ...]

### `do`
Marks task(s) on line ITEM# as done in todo.txt.
```shell
todo.sh do ITEM#[, ITEM#, ITEM#, ...]
```
### `help`
Display help about usage, options, built-in and add-on actions, or just the usage help for the passed ACTION(s).
```shell
todo.sh help [ACTION...]
```
### `list`
Displays all tasks that contain TERM(s) sorted by priority with line numbers. Each task must match all TERM(s) (logical AND); to display tasks that contain any TERM (logical OR), use `"TERM1\|TERM2\|..."` (with quotes), or `TERM1\\|TERM2` (unquoted). Hides all tasks that contain TERM(s) preceded by a minus sign (i.e. `-TERM`).
If no TERM specified, lists entire todo.txt.
```shell
todo.sh list [TERM...]
todo.sh ls [TERM...]
```
### `listall`
Displays all the lines in todo.txt AND done.txt that contain TERM(s) sorted by priority with line numbers. Hides all tasks that contain TERM(s) preceded by a minus sign (i.e. `-TERM`).
If no TERM specified, lists entire todo.txt AND done.txt concatenated and sorted.
```shell
todo.sh listall [TERM...]
todo.sh lsa [TERM...]
```
### `listaddons`
Lists all added and overridden actions in the actions directory.
```shell
todo.sh listaddons

If TERM specified, considers only tasks that contain TERM(s).
```shell
todo.sh listcon [TERM...]
todo.sh lsc [TERM...]
```
### `listfile`
Displays all the lines in SRC file located in the todo.txt directory, sorted by priority with line numbers. If TERM specified, lists all lines that contain TERM(s) in SRC file. Hides all tasks that contain TERM(s) preceded by a minus sign (i.e. `-TERM`).
Without any arguments, the names of all text files in the todo.txt directory are listed.
```shell
todo.sh listfile [SRC [TERM...]]
todo.sh lf [SRC [TERM...]]
```
### `listpri`
Displays all tasks prioritized PRIORITIES. PRIORITIES can be a single one (A) or a range (A-C). If no PRIORITIES specified, lists all prioritized tasks. If TERM specified, lists only prioritized tasks that contain TERM(s). Hides all tasks that contain TERM(s) preceded by a minus sign (i.e. `-TERM`).
```shell
todo.sh listpri [PRIORITIES] [TERM...]
todo.sh lsp [PRIORITIES] [TERM...]
```
### `listproj`
Lists all the projects (terms that start with a `+` sign) in todo.txt. If TERM specified, considers only tasks that contain TERM(s).
```shell
todo.sh listproj [TERM...]
todo.sh lsprj [TERM...]
```
### `move`
Moves a line from source text file (SRC) to destination text file (DEST). Both source and destination file must be located in the directory defined in the configuration directory. When SRC is not defined it's by default todo.txt.
```shell
todo.sh move ITEM# DEST [SRC]
todo.sh mv ITEM# DEST [SRC]

```
### `replace`
Replaces task on line ITEM# with UPDATED TODO.
