Tofrodos 2.1.1

• [Unix-type systems] fixed bug where Tofrodos was unable to
  convert a file in a directory that is not writeable by the user,
  even though the file itself is writeable.

Update (22 April 2026): if you are compiling for a Unix-type
system, get the tofrodos-2.1.1-source.tar.gz below, instead of
the automatically generated Source.tar.gz. I corrected the wrong
version number and date in fromdos.1 (man page). (It was still
showing 2.1.0.) There were no other changes. Alternatively, you
can clone from the head of the main repository, which has the
corrected fromdos.1. Or, if you prefer, you can just generate
the fromdos.1 yourself using the fromdos.1 target in makefile.vs,
but that will require you to use Windows.
