Display only the specified range when blaming

[jeenuv]

git blame supports -L option with which we can supply a range of lines to blame, and git outputs the blame for only those lines. This comes in handy when invoking from within an editor, say Vim. For example, to view the blame from lines 2000 to 2020, I could say :!git blame -L2000,2020 -- %.

Two issues with tig:

• tig does accept the same option. However, tig outputs all lines in the file. This means, for the example above, even though I'm interested in the 20 lines towards the bottom, tig shows the whole file, and I've to scroll 2000 lines for the view I'm interested in. Any chance this can supported?
• To tig, I've to specify it as -L2000,2020; it seems to be confused if I say -L 2000,2020, with white space after -L.

This is a really old issue that recently got fixed, but for what it's worth, I used the +<number> parameter (Show the first view with line visible and selected) to tig to solve this problem:

nmap <silent> <Leader>l :silent :execute "!tig blame " . shellescape(expand("%")) . " +" . line(".") <CR>:redraw!<CR>

Hitting <Leader>l opens the file in tig blame, with the line the cursor in vim was at, highlighted and centered. Hitting q returns to vim. Really handy.
