 We just upgraded our ffmpeg installations with the latest commit (648b422)
 from git and directly saw some failures with the HLS MUXERs
 'delete_segments' flag.

 Reproduce it like this:


 {{{
 ffmpeg -i input.ts -sn -map 0:v:0 -map 0:a:0 -c copy -b:v 3500k -hls_time
 3 -hls_list_size 3 -hls_flags
 append_list+omit_endlist+delete_segments+discont_start+program_date_time
 -master_pl_name master.m3u8 -f hls /tmp/hls/8387/vs_%v/playlist.m3u8

 }}}

 The error that will be generated is,
 {{{
 [hls muxer @ 0x5633fbf32d00] failed to delete old segment
 /tmp/hls/8387/vs_0playlist0.ts: No such file or directory
 }}}

 Note how there is a missing "/" after "vs_0".

 My known good commit is 8a1fc95 (unfortunately it is from 2018).
