--prompt= option doesn't work with --intr= option.

[arcmags]

Setting a prompt doesn't work when the --intr= option is used.

LESS='--prompt=test' less <file> sets the prompt to test as expected, while the following command fails to set the prompt:

LESS='--intr=c --prompt=test' less <file>

Version: less 643

Since the --intr option takes a string parameter, it needs to be terminated with a dollar sign, like

LESS='--intr=c$ --prompt=test' less <file>

Since only the first character or two characters (in the case of a caret followed by a character) are significant, the dollar sign requirement is somewhat nonintuitive. I will leave this issue open as an enhancement request to not require the dollar sign.

Fixed in 3440a1d.
The --intr option, as well as a few other options which take a string parameter, can be terminated with a space as well as with a dollar sign.
