gdb: Avoid trailing whitespace when pretty printing
While writing a new test for 'set print pretty on' I spotted that GDB will sometimes add a trailing whitespace character when pretty printing. This commit removes the trailing whitespace and updates the expected results in one tests where this was an issue. I've added an extra test for 'set print pretty on' as it doesn't seem to have much testing. gdb/ChangeLog: * cp-valprint.c (cp_print_value_fields): Don't print trailing whitespace when pretty printing is on. gdb/testsuite/ChangeLog: * gdb.base/finish-pretty.exp: Update expected results. * gdb.base/pretty-print.c: New file. * gdb.base/pretty-print.exp: New file.
