Hello, This is a small addition to a recent change: 1cec27a7f0e5c7bdc44a88ef51af09f87a8cbc24 grep: use errno consistently in write diagnostics
With the above change, if SIGPIPE is set to 'ignore' (e.g. by the shell or python), then grep would exit with "write error: Broken Pipe". Based on recent suggestion from Pádraig Brady ( http://lists.gnu.org/archive/html/coreutils/2016-04/msg00004.html ) perhaps it would be better to have special case for EPIPE and exit silently (as if SIGPIPE was not ignored and terminated the program?). Patch attached for such modification. One issue of which I'm not certain: I assumed that if 'prline' was called, a match was found. Thus, EPIPE will result in exit(EXIT_SUCCESS) indicating a match. Comments welcomed, - Assaf
