unpadding capitalized hallucinatory monster names

Two semi-related patches within the span of less than three days and
I overlooked the overlap.  When the() deals with a capitalized string,
it calls CapitalMon() to check whether the string matches a monster
and if so whether usage should be "the Monster" (Oracle or Olog-hai
for example) or just "Monster" (Medusa).  The first time that gets
called, it collects all capitalized non-the Monsters from both mons[]
and the bogusmon file.  The latter just got changed to pad short
lines, and that works fine for selecting hallucinatory monsters at
random via get_rnd_text(), but non-the Monster collection processes
the bogusmon file directly and wasn't updated to strip the padding.
