If it would fall under "SELFQUOTING" then yes (but I really don't
understand what the doc string is trying to tell me there and what would
be used for comparison).  It seems that a string constant is not
self-quoting during compilation (the byte-compiler complains about an
"Unknown upattern `pdf'"), most likely due to the pre-expansion of the
macro before compilation.  Also the string constant "pdf" compiled ionto
the code can not necessarily match itself when compared to a string
stored in a variable, although at least in interpretation mode this
works.  On the other hand a backquoted QPattern where QPattern is a
STRING(constant) does use "equal" for comparison and this is what we
want, plus the bytecompiler seems to like that form better than the
first.

Anyway, pcase is nice when you need it, but in this case I'm not
convinced its worth the trouble.  It doesn't even put enough syntactic
sugar on it to make the code more readable.
