Mahmoud Al-Qudsi 8f166cbb2a Prevent fish from crashing if non-essential terminfo strings not found
On systems where the terminfo for TERM does not contain a string for
attributes such as enter_underline_mode, etc. fish was crashing with a
fatal error message and a note to email the developers.

These are non-essential text attribute changes and should not trigger
such a failure.
