gdb: Fix skip of `\r` before `\n` in source output
In this commit:
commit 62f29fda90
Date: Tue Oct 9 22:21:05 2018 -0600
Highlight source code using GNU Source Highlight
A bug was introduced such that when displaying source code from a file
with lines `\r\n` GDB would print `^M` at the end of each line.
This caused a regression on the test gdb.fortran/nested-funcs.exp,
which happens to have `\r\n` line endings.
gdb/ChangeLog:
* source.c (print_source_lines_base): Fix skip of '\r' if next
character is '\n'.
