https://gerrit.osmocom.org/#/c/12227/3/src/gprs/sgsn_auth.c
File src/gprs/sgsn_auth.c:

https://gerrit.osmocom.org/#/c/12227/3/src/gprs/sgsn_auth.c@58
PS3, Line 58: 		return true;
The docstring says the imsi is truncated if we return true from this function.
"truncated" implies that dst contains all imsi data up to MAX_DIGITS, and any remaining imsi data beyond MAX_DIGITS will be missing from dst.
But in fact, when we return true here, the destination buffer is still empty - it does not contain any imsi data!
So this is a contradiciton.

I cannot actully tell what this code intends to do.
It looks to me like either the docstring or the code should be fixed.
