completion: make compatible with zsh
Modify git-completion.bash so that it also works with zsh when using
bashcompinit. In particular:
declare -F
Zsh doesn't have the same 'declare -F' as bash, but 'declare -f'
is the same, and it works just as well for our purposes.
${var:2}
Zsh does not implement ${var:2} to skip the first 2 characters, but
${var#??} works in both shells to replace the first 2 characters
with nothing. Thanks to Jonathan Nieder for the suggestion.
for (( n=1; "$n" ... ))
Zsh does not allow "$var" in arithmetic loops. Instead, pre-compute
the endpoint and use the variables without $'s or quotes.
shopt
Zsh uses 'setopt', which has a different syntax than 'shopt'. Since
'shopt' is used infrequently in git-completion, we provide
a bare-bones emulation.
emulate -L bash
KSH_TYPESET
Zsh offers bash emulation, which turns on a set of features to
closely resemble bash. In particular, this enables SH_WORDSPLIT,
which splits scalar variables on word boundaries in 'for' loops.
We also need to set KSH_TYPESET, to fix "local var=$(echo foo bar)"
issues.
The last set of options are turned on only in _git and _gitk. Some of
the sub-functions may not work correctly if called directly.
