Thanks, that should greatly improve the efficiency of fontification in
due time.

Based on my prior experience with Termux, I suspect that the Emacs home
directory should work.  Termux is able to both build and launch programs
in that directory, and I suspect also dlopen () libraries, though I have
not tried that.

P.S: I noticed that the Termux wiki lists some file managers that
integrate with SAF, and hence, should be able to access the home
directory on devices with poor built-in file managers:
https://wiki.termux.com/wiki/Internal_and_external_storage

While the manual should probably skirt from naming specific file
managers, it could be good to name what a file manager needs to be able
to access the Emacs home directory (namely, SAF support).

Thanks in advance.
