Confirm merge from FromPublicMasterBranch to master to sync with https://github.com/MicrosoftDocs/cpp-docs (branch master) (MicrosoftDocs#566)

* Update cricheditctrl-class.md

LineLength is a wrapper of EM_LINELENGTH, which returns length in characters not bytes.

* Update csettingsstore-class.md

contraction between the meaning of bAdmin in the parameters and remarks section of CSettingsStore::CSettingsStore

* Update clistbox-class_23.cpp

the buffer required by later code would be 16 bytes in ANSI and 32 bytes in Unicode, preallocating 10 bytes is useless.

* Fix unwind opcode values

* Update algorithm.md

Fix minor typo in Remarks section

* Undesired indentation in CFile.

Fix for undesired indentation in CFile constructor documentation.

* Update cricheditctrl-class.md

clarify that length is in TCHARs, add situations when index is out of bound, and when there's a carriage return based on EM_LINELENGTH docs

* Update compiler-warning-level-4-c4295.md

Clarify warning intent and ways to fix it, per comment by Kinichiro_Inoguchi

* Fix type error on the namespace

* Merge to live for offline publishing (MicrosoftDocs#532)
