Move mandoc_isdelim() back into libmdoc.h. This fixes an unreported

error where (1) -man pages were punctuating delimiters (e.g., `.B a ;')
and where (2) standalone punctuation in -mdoc or -man (e.g., ";" on its
own line) would also be punctuated.  This introduces a small amount of
complexity of mdoc_{html,term}.c must manage their own spacing with
running print_word() or print_text().  The check for delimiting now
happens in mdoc_macro.c's dword().
