Subject: [PATCH] speller: don't add an extra newline when saving the text to a
 tempfile

Set the NO_NEWLINES flag to achieve this.  And move the saving and
restoring of the global flags to the main speller routine, so the
flags aren't saved and restored for each internal spell fix.

This fixes https://savannah.gnu.org/bugs/?53742.
