File X contains a line with:

#else

Grepping:

case 1: 'grep -Ew -e "#else" X' returns "0":
#else

case 2: 'grep -E -e "\<#else\>" X' returns "1":

Same for -G

-F returns "0" for first case.

Although grep is operating as documented here, the documentation could be 
better. I installed the attached patch to try to clear things up. Thanks for 
reporting the problem.
