histedit: add a config allowing changing histedit rule line length limit

Browse Source 
Since many users are using terminals wider than 80 chars there should be an
option to have longer lines in histedit editor.

Even if the summary line is shorter than 80 chars after adding action line
prefixes (like "pick 7c2fd3b9020c") it doesn't fit there anymore. Setting
it to for example 110 would be a  nice option to have.

can customise this behaviour by setting a different length in your
