From: SZEDER Gábor <szeder@xxxxxxxxxx>
Git's bash completion currently doesn't work when certain git options
are specified, e.g. 'git --no-pager <TAB>' errors out with "error:
invalid key: alias.--no-pager".
The main _git() completion function finds out the git command name by
looping through all the words on the command line and searching for
the first word that is not a known option for the git command.
Unfortunately the list of known git options was not updated in a long
time, and newer options are not skipped but mistaken for a git
command. Such a misrecognized "command" is then passed to
__git_aliased_command(), which in turn passes it to a 'git config'
query, hence the error.
Currently the following options are misrecognized for a git command:
-c --no-pager --exec-path --html-path --man-path --info-path
--no-replace-objects --work-tree= --namespace=
To fix this we could just update the list of options to be skipped,
but the same issue will likely arise, if the git command learns a new
option in the future. Therefore, to make it more future proof against
new options, this patch changes that loop to skip all option-looking
words, i.e. words starting with a dash.
We also have to handle the '-c' option specially, because it takes a
configutation parameter in a separate word, which must be skipped,
too.
