imerge abort

[abitrolly]

I am trying to summarize how to abort imerge, because there is no such command yet.

TL;DR

git merge --abort
git switch $(git rev-parse --abbrev-ref HEAD | cut -d/ -f2)
imerge remove

First command aborts merge.
Second finds the original branch name and switches to it.
Third cleans up imerge branch.

Demonstration how the branch detection works.

✗ git rev-parse --abbrev-ref HEAD
imerge/tests-root-stub
✗ git rev-parse --abbrev-ref HEAD | cut -d/ -f2
tests-root-stub

Should be possible to add it to Python code.
