GNU nano (5.4) - nosearchwrap

• While performing textual search, many editors, for instance Sublime, support toggling the option Wrap, which is to wrap past end-of-file and proceed searching. It will be nice if Nano can have this too!

New rcfile option:

set nosearchwrap
    Don't wrap around to the start or end of the buffer when performing search or replace.

New program option:

--nosearchwrap
    Don't wrap around to the start or end of the buffer when performing search or replace.

How to compile

Please refer to README.GIT for more details.

1. Install the dependencies: apt install autoconf automake autopoint gcc gettext git groff make pkg-config texinfo

2. Run ./autogen.sh.

3. After that, just do the normal ./configure, make and make install.
