sqlite/tool/mksourceid.c
drh 19be1b631b Fix a bug in tool/mksourceid.c: 
The mksourceid.c program was incorrectly including the "# Remove this line"
line of the Fossil-generated "manifest" file in the SHA3 hash.  That means
that all SQLITE_SOURCE_IDs for trunk versions going back to
check-in [30966d56] (2017-08-22) are incorrect.

/*
** Run this program with a single argument which is the name of the
