hylafax-v4.0pl1: "Yes" in modem config doesn't work

["Jonathan I. Kamens" <jik@kamens.brookline.ma.us>]

The hylafax config(5) man page claims that "Yes" can be used as a true
boolean value in config file entries, but it appears that the version
of streq() inherited by the getBoolean() function does case-sensitive
comparisons, so "Yes" doesn't work but "yes" does.

I'm not sure which is wrong, getBoolean() or the man page, but I
suspect getBoolean :-).
