Description
Description of the problem or steps to reproduce
When doing a find, a regex only needs single backslah characters to work, e.g. \b \w etc.
However when going a replace, you need to use double backslashes, e.g. \\b \\w etc.
E.g. Given the following file...
hello world
Ctrl-F \bhello successfully finds the "hello"
Ctrl-E replace \bhello goodbye does not find the "hello" (Displays the message Nothing matched bhello)
Ctrl-E replace \\bhello goodbye successfully finds the "hello" and replaces it with goodbye.
Specifications
Tried with both 1.40 and 1.41 nightly and both exhibit the same behaviour

Research direction
Start by reproducing the reported behavior in micro using Ctrl-F and Ctrl-E with the provided hello-world example. Trace the find and replace command entry points to compare how regex backslashes are handled. Done means replacement accepts the same single-backslash regex syntax as find while preserving the documented replacement behavior.
