find.1: set filenames in italics

man-pages(7) says:
  Filenames [...] are always in italics, except in the SYNOPSIS
  section, [...]

Set filenames in italics, respectively change from boldface to italics.
While at it, mark whitespaces in commands as non-breakable via '\ '
to avoid unwanted hyphenation in the middle of commands.

* find/find.1 (-regex): Do the above.
(-exec,-execdir,-fprint): Likewise.
