-This won't print anything unless Gutentags figures that `ctags` is running in
-the background. This is done by checking a `.lock` file next to the tag file,
-but there's also some optimization before that to not slow down Vim. Note that
-the `.lock` file can sometimes be left around incorrectly by the background
-process, and you may need to clean it up. See |:GutentagsUnlock|.
+Because Gutentags runs the tag generation in the background, the statusline

-When Gutentags thinks `ctags` is still running, it will print the string
-"TAGS" by default. You can customize it: >
