description:
lint: fix type warnings in emit1.c

The plain character strings in strg_t are saved as an array of unsigned
char.  When such a character is passed to ch_isdigit, it requires a
cast.  This is exactly the situation that ch_isdigit tried to avoid in
the first place.

No functional change.
