 `msgcheck` performs various checks on gettext files (with extension ".po"):
 
 * compilation (with command `msgfmt -c`)
 * for each translation:
-  * number of lines in translated strings
-  * whitespace at beginning/end of strings
-  * trailing whitespace at end of lines inside strings
-  * punctuation at end of strings
-  * spelling (messages and translations)
+** number of lines in translated strings
+** whitespace at beginning/end of strings
+** trailing whitespace at end of lines inside strings
+** punctuation at end of strings
+** spelling (messages and translations)
 
 The script requires Python >= 2.7.
 
 Module `pyenchant` is required if spelling is checked (option `-s`).
