allow more characters in passwords read from file

strip() with no arguments would mean that a password read from a file
could not contain a leading space.  While that is unusual, it is also
true that in such an edge case, the use of the password file would be
more likely to manage the weird string.

removesuffix('\n') should be the most targeted possible cleanup.
