Enforced egrep warning by an if/then check

[Ralf Mardorf <ralf-mardorf@xxxxxxxxxx>]

Hi,

I'm uncertain, if it makes sense to file a bug report against the
xfce4-dev-tools or not. Actually upstream has got a reason to do this
;), but on Arch Linux it results in unwanted and annoying warnings :(.

$ grep egrep /usr/bin/xdt-autogen -A3
  if type egrep >/dev/null 2>&1; then
    EGREP=egrep
  else
    EGREP="grep -E"
  fi

One time I reported an egrep related warning issue against the rtirq
community package and upstream, but I didn't report it against e.g.
AUR's ventoy-bin. However, the above if/then issue is something very
special, since a workaround does cause the warnings in this particular
case. The grep package does also provide a workaround. IOW two
workarounds collide with each other :D.

Regards,
Ralf
