From b45b9e3cde3c8b803fc2c4fbdb784fc378ced24d Mon Sep 17 00:00:00 2001 From: sheldonh Date: Wed, 1 Mar 2000 14:50:24 +0000 Subject: Remove single-space hard sentence breaks. These degrade the quality of the typeset output, tend to make diffs harder to read and provide bad examples for new-comers to mdoc. --- share/man/man4/ti.4 | 48 ++++++++++++++++++++++++++++++++---------------- 1 file changed, 32 insertions(+), 16 deletions(-) (limited to 'share/man/man4/ti.4') diff --git a/share/man/man4/ti.4 b/share/man/man4/ti.4 index 383fb56..294098d 100644 --- a/share/man/man4/ti.4 +++ b/share/man/man4/ti.4 @@ -43,19 +43,26 @@ Alteon Networks Tigon I and Tigon II gigabit ethernet driver The .Nm driver provides support for PCI gigabit ethernet adapters based on -the Alteon Networks Tigon gigabit ethernet controller chip.
