Subject: top: avoid potential truncation with 'Inspect' feature
X-Git-Tag: v3.3.13rc1~22

top: avoid potential truncation with 'Inspect' feature

As it turns out, that Ukrainian 'demo' text supporting
the '=' command was 152 bytes long, up from an English
version of 80 bytes. Unfortunately, the buffer used to
format all such strings was insufficient at 128 bytes.

Depending on the width of one's terminal, some strange
result could be experienced when a multi-byte sequence
was truncated. So, this just makes that buffer bigger.
