compatibility to GNU grep

I just noticed, that on my system (Arch Linux, might test this on Void Linux tonight) grep uses regular expression, while ugrep uses extended regular expression.
Personally i don't mind, this behaviour, as I am more comfortable with extended regex. But the readme boasts about full compatibility to BSD/GNU grep and this difference could break scripts.
(I don't know how BSD grep behaves)

When using ugrep as an alias as suggested, then you control this using options i.e. -G and -E. When the binary is renamed or copied to grep, then option -G is used. Rename to egrep option -E is used, rename to fgrep option -F is used. Therefore, ugrep is compatible to grep and automatically uses the correct regular expression mode.
