How to fix git log output (missing lines in less)?
I have two different servers each running a Ubuntu installation. On both of them, I have set env LESS=-FerX which makes sure that git log output is displayed nicely. Also, line wrapping is turned on.
On one of the servers, if I run git log and there are dynamically-wrapped lines, the topmost lines disappear.

- How to revert to changes I committed?
- Setting up Git osxkeychain error
- Accidentally deleted many hidden files with “git clean -fd” and now I cannot install Ruby
- Automatic Xcode Git Commit Prompts
- Gitlab : add quick-actions in commit comments
For example:
log --pretty='format:%C(3)[%h] %Cgreen%an%Creset%n %cd %s %Cred%d%Creset' --graph
Output on Server 1:
* [1234457] John Doe
| Date fooooo bar baz fooooo bar baz fooooo bar baz fooooo bar baz fooooo bar baz
fooooo bar baz fooooo bar baz fooooo bar baz fooooo bar baz fooooo bar baz fooooo
bar baz
* [4567890] Richard Miles
| Date fooooo bar baz
:
Output on Server 2:
fooooo bar baz fooooo bar baz fooooo bar baz fooooo bar baz fooooo bar baz fooooo
bar baz
* [4567890] Richard Miles
| Date fooooo bar baz
* [0815123] Mary Major
| Date fooooo bar baz fooooo bar baz fooooo bar baz

Any idea how to fix this?

Again, I find the answer to my own question only minutes after asking.
Turns out the problem was the -r parameter to less. It should have been a -R instead.
From the manpage:
-R or --RAW-CONTROL-CHARS
Like -r, but only ANSI "color" escape sequences are output in "raw" form.
Unlike -r, the screen appearance is maintained correctly in most cases.
For some reson not known to me, the lower-case -r works fine on of the other server.
Perhaps you know this, and you might have tried it, but since you don’t mention it:
man git config contains (emphasis mine):
core.pager
The command that git will use to paginate output. Can be overridden with the GIT_PAGER environment variable. Note that git sets the LESS environment variable to FRSX if it is unset when it runs the pager. One can change these settings by setting the LESS variable to some other value. Alternately, these settings can be overridden on a project or global basis by setting the core.pager option. Setting core.pager has no affect on the LESS environment variable behaviour above, so if you want to override git’s default settings this way, you need to be explicit. For example, to disable the S option in a backward compatible manner, set core.pager to less -+$LESS -FRX. This will be passed to the shell by git, which will translate the final command to LESS=FRSX less -+FRSX -FRX.
