[Rd] Possible bug with a regex pattern

[Etienne Sanchez]

Dear list,

The following behaviour looks like a bug:

grepl("ab{,2}c", "abbbc")
# [1] TRUE

I would expect either FALSE or an "invalid regex" error.

More details can be found in the question I originally asked here:

I've also opened an issue on the TRE github:

Best,

Etienne
