From: Tom Tromey Date: Mon, 11 Sep 2023 15:21:26 +0000 (-0600) Subject: Update Python signal-handling documentation X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=14432bde076fdee66e6163993eadf592742935da;p=binutils-gdb.git Update Python signal-handling documentation I noticed a typo in the "Basic Python" node, and when fixing it realized that the paragraph could use a link to the block_signals function. This patch is the result.
