[GRASS-dev] [grass-code I][379] r.in.wms incorrect flag

[Daniel Calvelo]

If this is a BSD sed issue (which it seems to be, this being MacOSX),
the only portable thingie is:

s/[Ee][Vv][Ee][Rr][Yy]/possible capitalization as alternations/

As a MacOSX-only workaround, define SED="perl -pe" then call $SED
's/aa/AA/i' instead of sed 's/aa/AA/i', which works if:

1) Perl is installed (always true for MacOSX and linuxen)
2) A compatible subset of commands (e.g. simple s///i) is used in the sed code
3) The regexps don't use backreferences and capturing parenthesis
(which works differently in perl and sed)

BTW does BSD sed recognize \w?


OTOH, given that in r.in.wms the /i flags are used after a grep which
IS case-sensitive, they can be removed, AFAICT. Can anybody try this?
