sub and gsub treat \\ incorrectly (PR#13454)
Sub and gsub treat \\ replacement pattern incorrectly
I expect
sub("a","\\", "a", perl=T)
to produce
[1] "\"
instead it generates
[1] ""
On the other hand, if I run
sub("a","\\\\", "a", perl=T)
it correctly outputs
[1] "\\"
The same issue applies to gsub.
