pcre2_substitute() now sets the output buffer length to PCRE2_UNSET (~0) if the output buffer is determined to be too small. This change keeps track of the buffer size separately where pcre2 can't touch it. A better fix would be to let pcre2 tell fish what size buffer it needs. This can be done with PCRE2_SUBSTITUTE_OVERFLOW_LENGTH, but this requires pcre2 10.21 or later (released January 12), which may be too new to introduce as a dependency at this point. Fixes #2743
