Option --translate doesn't work in most places. And when it works, there is no info about.

Hi,
I'm using --translate (translate from source language to English), and sometimes the transcription is done.
But many times transcription it is not done, and I see note about the language or text appears in the origin language.
Also, the results are missing information about the use of transcription, having this information would be very helpful.

I'm running Whisper CPP on several long recordings 20min - 2h with default settings, 15 threads (-p 1 -t 15).
I've tried multilanguage models: base, small, medium, large.
I'm using WAV files, not streaming.

Examples:
model=small:
[00:32:12.000 --> 00:32:15.000] (speaking in Spanish)
[00:33:18.000 --> 00:33:27.000] (speaking in Spanish)
[00:33:28.000 --> 00:33:31.000] (speaking in Spanish)
[00:33:31.000 --> 00:33:45.000] (speaking in Spanish)
[00:33:45.000 --> 00:33:48.000] (speaking in Spanish)

model=small, , --max-len 1

[00:02:36.480 --> 00:02:37.960] [SPEAKING SPANISH]
[00:02:37.960 --> 00:02:40.960] [SPEAKING SPANISH]
[00:02:40.960 --> 00:02:41.960] [SPEAKING SPANISH]
[00:02:41.960 --> 00:02:42.960] [SPEAKING SPANISH]

[00:01:42.010 --> 00:01:47.980] ish
[00:01:47.980 --> 00:01:50.000] ]

I see a lot of similar cases.
Love Whisper CPP,

For me it worked with the large one.

You'll want to also add the -l es flagging to avoid default translation.
