[FFmpeg-devel] [PATCH V1] fftools/cmdutils: Fix break command dump for -map option

[Jun Zhao]

From: Jun Zhao <barryjzhao at tencent.com>

Before this fix, ffmpeg -h full | grep map get the command dump
like:

-map [-]input_file_id[:stream_specifier][,sync_file_id[:stream_s  set input stream mapping
                                                               ^
                                                               |
							    truncated
after this fix, we can get full option dump.
