Fix completion when password name contains quotes

[pdecat]

This PR fixes shell completion when some passwords names contain single or double quotes.

Without this change, completion either returns nothing or inconsistent results depending on the number of quotes passwords matching the requested completion contain.

TODO:

• add unit tests.

Lgtm, thanks!

Thanks for the quick review @AnomalRoil!

CommitCheck — Your PR description is not valid.

Not sure why this check fails, any idea?

You need to add a RELEASE_NOTES tag as explained here, I think:

Thanks, should have looked there 🤦‍♂️

Added the RELEASE_NOTES tag but CommitCheck is still complaining: Your PR description is not valid.

Should I have used a template of some sort or link to an issue for the PR description?

I'm not sure what's wrong. We can merge that nonetheless, so don't worry.

Btw, I've just tested your code locally and it doesn't seem to work like I expected it.
What are the steps you use to reproduce the issue in the first place?

Does it display with a " in the completion output on your side now?

[AnomalRoil]

Ah, I could reproduce it, the default completion for bash was calling my system-wide install of gopass:

$ ./gopass --generate-bash-completion | grep tests
tests/tes\\\"t
$ gopass --generate-bash-completion | grep tests
tests/tes"t
