Subject: m_getfld.c: Alter Ungetc() to die if it can't rewind.
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/bc2e83953a3c09e6416e335eb6827aaa483a39f6?hp=bc2e83953a3c09e6416e335eb6827aaa483a39f6

m_getfld.c: Alter Ungetc() to die if it can't rewind.

It used to return EOF to the caller in this case, but none of the three
callers bothered checking.  And the other return value of a `peek' of
the character that would next be read was also unused.
