Subject: [PATCH] Add urfave_cli_no_docs build tag

This removes the resulting binary dependency on cpuguy83/md2man and
russross/blackfriday, which saves more than 400 KB (more than 300 KB
once stripped) from the resulting binary.

Document this in README.

+### Build tags
+
+You can use the following build tags:
+
+#### `urfave_cli_no_docs`
+
+When set, this removes `ToMarkdown` and `ToMan` methods, so your application
+won't be able to call those. This reduces the resulting binary size by about
+300-400 KB (measured using Go 1.18.1 on Linux/amd64), due to less dependencies.
+
 ### GOPATH
 
 Make sure your `PATH` includes the `$GOPATH/bin` directory so your commands can
