Invalid search regex crashes the program with a traceback

[ghost]

I've accidentally hit enter after /? and the program crashed with the following traceback:

Traceback (most recent call last):

You should probably catch this exception and instead display a relevant error message about an invalid regexp search string.

It's not a critical bug, yet epy seems to lose the current position in the file when crashing like that. Without looking at the code, I can assume it only saves position when exitting gracefully.

Thanks so much for the advice mate, will fix it later...

Hey there just fixed this: https://github.com/wustho/epy/commit/3349f99ed28b5c9884308fba969e7ec554a60415

Oh make sure you delete recursively config dir ~/.config/epy because I do some heavy config/state file update without considering backward compatibility, sorry.

Reinstalled the latest version and everything is fine now, thank you.
