Push current branch to branch of same name.
This is useful for new branches as I almost always push those with:
```
git push -u origin "$(git branch --show-current)"
```
The changes are only shown in the editor and do not land in the final
commit message.
For that setting the git-commit-last-msg function and the commit-msg
hook had to be updated.
The function is now a standalone function instead of anonymous and
uses every line until the first comment in COMMIT_EDITMSG discarding the
new information too.
The hook breaks now when checking line lengths when the changes start
since for some weird reason they are passed together with the rest of
the message instead of being deleted like the comments.
Jump between file sections and commits by using n and N. Taken from:

Remove FX flags since they are incompatible with the pattern search:
When showing a small change that fits on less than the screen height,
the rest of the screen is filled with ~ lines instead of quitting the
pager. This behaviour is annoying and thus the flags are deactivated.
Since git adds them per default they have to be explicitly disabled.
Use Github credentials when in Projects/github folder.
All other custom github projects are stored in user.config.
Use 8 spaces for tabs to see whitespace error in git diffs.
