+BUGS
+----
+When using the deprecated `[section.subsection]` syntax, changing a value
+will result in adding a multi-line key instead of a change, if the subsection
+is given with at least one uppercase character. For example when the config
+looks like
+
+--------
+ [section.subsection]
+ key = value1
+--------
+
+and running `git config section.Subsection.key value2` will result in
+
+--------
+ [section.subsection]
+ key = value1
+ key = value2
+--------
