Line endings

The command 177, which is used to indicate a line-end in various places, is now a robust command when used within arguments such as section titles. Also, because it is often necessary to distinguish which type of line is to be ended, we have introduced the following new command; it has the same argument syntax as that of 178.

179 [<<#349#>vertical-space<#349#>>]

One example of its use is when the text in the last column of a 180 environment is set with 181; then 182 can be used to indicate the end of a row of the 183, whilst 184 will indicate the end of a line of text in a paragraph within the column. This command can be used in the 185 environment as well as 186, and also the extended versions of these environments offered by the <#351#>array<#351#> and <#352#>longtable<#352#> packages in the tools collection.
