 'viminfo' option is a string containing information about what info should be
 stored, and contains limits on how much should be stored (see 'viminfo').
 
+Merging happens in two ways.  Most items that have been changed or set in the
+current Vim session are stored, and what was not changed is filled from what
+is currently in the viminfo file.  For example:
+- Vim session A reads the viminfo, which contains variable START.
+- Vim session B does the same
+- Vim session A sets the variables AAA and BOTH and exits
+- Vim session B sets the variables BBB and BOTH and exits
+Now the viminfo will have:
+   START - it was in the viminfo and wasn't changed in session A or B
+   AAA   - value from session A, session B kept it
+   BBB   - value from session B
+   BOTH  - value from session B, value from session A is lost
+
+For some items a timestamp is used to keep the last changed version.  Here it
+doesn't matter in which sequence Vim sessions exit, the newest item(s) are
+always kept.  This is used for:
+- The command line history.
+- The search string history.
+- The input-line history.
+- Contents of non-empty registers.
+- The jump list
+- File marks
