#3 Fix displaying branch names with numbers, hyphens and underscores

I usually have branch names that might include numbers, hyphens and/or underscores.

Here is one example of branch name wrongly displayed:

# Before applying this fix:
[ 6.07pm]0 ts@ts-kubuntu: + [ts_add_sk_l1]↓2≠1 ~/git/romcal/romcal_ts_add_sk_l10n
$ srcb

# After applying this fix:
[ 6.07pm]0 ts@ts-kubuntu: [ts_add_sk_l10n]↓2≠1 ~/git/romcal/romcal_ts_add_sk_l10n

Thanks for the patch.

I’m glad I could help. ;)
