At some point the completion code was refactored and in the event where
no explicit function description was passed into `resolve_description()`
it would attempt to use the `desc_func` parameter but pass in the
_remaining_ part of the completion rather than the full text, which
would obviously fail.
e.g. if completing `foo<TAB>`, for function `foobar` it would attempt to
find the description for a function named `bar` instead of `foobar`.
Closes#5206.
This reverts commit 9c63ad3209 until I can
figure out what is causing the assertion and test failures.
It *seems* to be that passing in the correct function name to the
description lookup is causing a previously present error to be realized,
but I can't yet be certain.

There's been no reproducible case entered for #5080, but the stack trace
indicates the problem is with env_get_pwd_slash() returning an empty
string, which isn't a string that terminates in `/`.
In addition to making the failure case to return the path `./` (which
has the benefit of having the same meaning as $PWD), trying a little bit
harder to retrieve the real PWD by using getcwd(3). While
get_current_dir(3) is documented as relying on PWD, getcwd(3) does not
mention any such caveats, so it's possible that it will work even if
something is breaking PWD.
Just a thought, but it's possible if due to some recursion PWD surpassed
some predetermined value (maybe PATH_MAX) that PWD (on certain platforms
or under certain enivronments) won't be set (hence the code that deals
with ERANGE errors from the getcwd(3) call).
Closes#5080.
As reported in fish-shell/fish-shell#5180, when the USER environment
variable is not set and fish is started, `get_runtime_path()` returns a
blank string. At some point in the past, this was called after
`setup_user()` in env.cpp, but this is no longer the case.
This commit removes the reliance on the $USER environment variable
entirely, and instead uses `getpwuid(geteuid()).pw_name` to retrieve the
current username.
Closes#5180.
For some reason I started getting literal \n appearing in Doxygen-generated
help files. These are coming from newlines in aliases defined in
Doxyfile.user. These should be safe to remove because they are HTML-specific
and there is still whitespace before them. Remove these newlines.
This didn't reproduce on Linux; Doxygen is full of mysteries.
