(print_wchar): Prefer 3-digit octal form. Fall back to hex if needed. * c-exp.y (c_parse_escape): Only allow 3 octal digits. gdb/testsuite * gdb.base/call-rt-st.exp: Update for change to escape output. * gdb.base/callfuncs.exp: Likewise. * gdb.base/charset.exp: Likewise. * gdb.base/constvars.exp: Likewise. * gdb.base/long_long.exp: Likewise. * gdb.base/pointers.exp: Likewise. * gdb.base/printcmds.exp: Likewise. * gdb.base/setvar.exp: Likewise. * gdb.base/store.exp: Likewise. * gdb.cp/ref-types.exp: Likewise. * gdb.mi/mi-var-child.exp: Likewise. * gdb.mi/mi-var-display.exp: Likewise. * gdb.mi/mi2-var-display.exp: Likewise. * gdb.base/charset.exp: Test octal escape sequence length.
