I'm currently using git annex to manage my entire file collection
(including tons of music and books) and I noticed how slow
autocompletion has become for files in the index (say for git add).
The main offender is a while-read-case-echo bash loop in
`__git_index_files` that can be readily substituted with a much faster
sed invocation. Here is my benchmark:
```
__git_index_files ()
{
local dir="$(__gitdir)" root="${2-.}" file;
if [ -d "$dir" ]; then
__git_ls_files_helper "$root" "$1" | while read -r file; do
case "$file" in
?*/*)
echo "${file%%/*}"
;;
*)
echo "$file"
;;
esac;
done | sort | uniq;
fi
}
time __git_index_files > /dev/null
__git_index_files ()
{
local dir="$(__gitdir)" root="${2-.}" file;
if [ -d "$dir" ]; then
__git_ls_files_helper "$root" "$1" | \
sed -r 's@^"?([^/]+)/.*$@\1@' | sort | uniq
fi
}
time __git_index_files > /dev/null
real 0m0.830s
user 0m0.597s
sys 0m0.310s
real 0m0.345s
user 0m0.357s
sys 0m0.000s
```
So you might redefine `__git_index_files` as above in your .bashrc after sourcing the git autocomplete script.
