I guess the biggest confusion is why scan_texmf_tree uses osdirs to search through non-texmf locations. And in doing so, what is the purposes of OSFONTDIR?

For TEXMF tree font directories, kpse returns the individual
subdirectories, AFAICT, so I felt there is no need to scan them
recursively, while OSFONTDIR is returned as is i.e. if I set
OSFONTDIR=~/.fonts, kpse will just return this so I had to scan it
recursively.

I admit the code is unnecessary complex and nit very well organized,
partly because it was written and rewritten partially across a period of
time and I didn't always know what I'm doing.
