This check is intended for ensuring that the profiles file can actually
be opened. The *actual* check is performed by the shell, not the read
utility, which won't even be executed if the input redirection (and
hence the test) fails.
If the test succeeds, though, using `read` here might actually
jeopardize the test result if there are no profiles loaded and the file
is empty.
This commit fixes that case by simply using `true` instead of `read`.
Known Bugs:
Will allow multiple letters in the () due to translation/unicode issues with regexing the key.
User input will probably bug out in a different locale.
