Comment # 9 on bug 1229795 from Michael Pujos

There is also this issue with directories with ':' in their name, which is
frequent for OBS repos (for example home:user:branches:games):

Example:

mkdir test:lol
cd test<TAB> 
cd test\:lol/    (<= completion)

Slso there is problem with completion for files in such folders if a backlash
does not precede the ':'   :

echo "TROLOLOL" > test:lol/blargh
ls test:lol/<TAB>  (=> no completion)
ls test\:lol/<TAB> (=> completion to test\:lol/blargh)
