 A possible fix for the make/sh bug with SIGINT:

 This makes 'sh -ec' consider SIGINT as an 'error' worth aborting, and
 stops the long 'make fetch' command on ^C as it should.
 
 The 'if (minusc) {..' code was recently added (rev 1.7 of eval.c), it
 seems to be the cause of the problems.
 
 Incidently, I could find no other shells that ignored SIGINT while doing
 a 'sh -c' command..  Is this code really legitimate??  It looks like a
 gratuitous incompatability with "other" systems...
